IMPROVEMENT IN NUT-LOCKS.

Specification forming part of Letters Patent No. 146,106, dated December30, 1373; application tiled November 26, 1873.

` `forth.

In order to enable Others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describel itsconstruction and Operation, referring to the annexed drawing, in which-Figure l is a perspective view, and Fig. 2 a

` side view, of my invention.

A A represent the ends of two adjoining railroad-rails, with IislrplatesB, fastened by bolts ai a and ynuts b b in the usual manner. On thebolts a a is placed a plate, O, before the nuts b b are screwed on. Thisplate C is v of such length that its ends will bear against the sides ofthe nuts b b on the bolts a af, and thereby lock the same, so that theycan- On the outer side of the plate C, near the center, is pivoted alatch, D, prol vided with a shoulder, offset, Or lug, Lat each hook, i,which, when the latch is turned `down p to lock the nuts, springs underthe lower edge of the plate G, and thereby locks the latch. The hook ican readily be sprung out away from the edge of the plate, when thelatch may be raised for unscrewing the nuts b b.

I am aware that a pivoted latch having an` upper catch at one end and alower catch at the other end to act upon the top of one nut and underthe bottom of the adjacent' nut is not new 5 hence Idisclaim such asbeing broadly my invention.

Having thus fully described my invention, what I claim as new, anddesire to 'secure by Letters Patent, is-

The pivoted latch D, provided with the hook t' and lugs d d,substantially as and for the pur poses herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this17th day of November, 1873.
